Healthworks At St. Mary's, Gym For Low-Income Women, Saved By Anonymous Donor

Sure, a fitness center can help a person get in shape and feel great. But is it a bit of a stretch for someone to describe her gym as "life-saving"?

Not necessarily -- if the gym in question is Healthworks at St. Mary's, in the Dorchester area of Boston. Since 2002, this small gym has provided completely free memberships to thousands of homeless and very low-income women.
